If you shout something loud enough and many people are saying it, does it become true? Some groups of people (include tech journalists and Linux advocates, such as Steven J. Vaughn-Nichols) have a psychological need to find Vista lacking. Mr. V-N has predicted that Vista will have all manner of problems, so his clear interest is to point out everything that is wrong with the OS. Who cares if he has to even make some stuff up?

"MS knows that DRM is bad for business, and just like Apple (who has just as much DRM in OS X and the iPod) has been in talks with the record companies to get rid of it. EMI is the first, MS is in talks with them right now"

If MS knew DRM was bad for business, they would not have infected Vista with it. They are thinking of selling DRM free music because the Apple/EMI deal has forced them to do so. MS is already planning the next DRM OS:

It would be worse for business to sell an OS that can't play HD-DVDs and Blue-Ray. An Apple/EMI didn't force them, everybody but the labels want to get rid DRM, DRM adds needless complexity and inflexibility to the OS.

Vista has no more DRM than OS X and iTunes. I'm not sure where you are getting your info from, but perhaps if you just did some googling, you'd see it is an industry wide problem, and not just MS's.
